Abstract

995,190. Transistor pulse circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Nov. 8, 1963 [Nov. 13, 1962], No. 44174/63. Heading H3T. A pulse generator comprises a capacitor 4 charged via normally conductive transistor 1 and an inductor 3 and discharged via an avalanche transistor 2 triggered by the voltage developed across the inductor 3 when the transistor 1 is made non-conductive. As described, the voltage across capacitor 4 is normally stabilized by a silicon diode 9 whilst the base voltage of transistor 1 is stabilized by a silicon diode 11. Transistor 1 is cut off by each 100 Mc./s. pulse at the base, the change in collector current being differentiated by inductor 3, the differentiated pulse being clipped by silicon diode 12 and used to trigger the avalanche transistor 2 which discharges capacitor 4 via resistor 10, giving a current pulse of 3 ns. having a rise time less than 1 ns. In Fig. 1 (not shown) diode 11 is replaced by a shunt capacitor having a time constant with resistor 7 of the same order as the duration of input pulse. Inductor 13 and diode 12 are also omitted.
